Description

The present invention relates to a wire binding unit provided at a binding position of a saddle stitch binding machine and binding a predetermined position of a paper bundle with a wire each time a paper bundle is supplied to the binding position.

This type of wire binding unit typically includes a pair of stitcher heads and a pair of clincher located below and facing the pair of stitcher heads during the initial setup of the saddle stitch binding machine. The distance between the pair of stitcher heads and the distance between the pair of clincher corresponding to the arrangement of the wire driving position of the paper bundle are automatically adjusted (for example, Patent Document 1, Patent Document 1, 2).

Then, each time the saddle stitch binding machine starts operation and a bundle of paper is supplied to the binding position, the pair of stitcher heads are lowered from the standby position toward the pair of clincher, and the stitchers are placed at two positions on the bundle of paper. The wire is driven by the head, the leg portion protruding downward from the paper bundle of the wire is bent by the clincher, and two places of the paper bundle are stitched with the wire (two wires are bound).

By the way, there is a method called 2-chome binding in saddle stitch binding. Two-chome binding is a method in which two impositioned signatures are used as one unit to perform saddle stitch binding, and then cutting to produce two booklets at the same time.

In 2-chome binding, it is necessary to drive wires into 4 places of the signature (paper bundle) and bind the booklets for 2 books at the same time (4 places of wire). Therefore, two more stitcher heads and two corresponding clincher will be added to the wire binding unit.
In this case, the expansion stitcher heads are attached to both outer sides of the pair of stitcher heads for two-place wire striking, and the additional clincher is attached to both outer sides of the pair of clincher for two-place wire striking. It is installed and the positions of the expansion stitcher head and the expansion clincher can be adjusted manually.

Then, the set of the stitcher head pair on one side and the corresponding clincher pair is used for wire binding of one of the two booklets, while the stitcher head pair on the other side and the corresponding clincher pair are used for wire binding. For wire binding of the other booklet of the two booklets, at the time of initial setting of the saddle stitch binding machine, first, depending on the arrangement of the two booklets, a pair of wires for two places The spacing between the stitcher heads and the corresponding spacing between the two-place clincher for the pair of wires are adjusted.

After that, depending on the arrangement of the wire driving position for each booklet, the distance between the stitcher head for two-place wire driving and the adjacent additional stitcher head, and the corresponding clincher and adjacent to it. The spacing between the expansion clincher is manually adjusted, and the spacing between the other two-wire stitcher head and the associated expansion stitcher head, and the corresponding expansion clincher and related expansion. The spacing between clincher is adjusted.
However, the position of the stitcher head and the clincher must be adjusted manually, which causes a problem that the adjustment work takes time.
